Where they occur, Field Mice
are generally the dominant small rodents. They are highly
adaptable and can survive in most habitats as long as these are
not too wet. (From woodland and forest to sand dunes.) Field mice
excavate burrows but nest above ground. Mainly nocturnal, they
have large, bulging eyes to give them good night vision.

They feed on a wide variety
of foods, including seeds, buds, invertebrates, fruit and fungi.
Their cheek teeth are low crowned.

This specimen is from St
Kilda. Considered a subspecies, St. Kilda mice, in common with
other island strains of field mice, have a buff coloured belly
and are larger than mainland field mice.
